Multifunction DC Consumption Meter DC Voltage Current Power Energy Consumption Meter Communication Module Ammeter Voltmeter Module(2)

Features:

1. It is mainly used to measure DC voltage, current, active power, frequency, and power consumption.
2. The current measurement range is 50A, 100A, 200A, and 300A depending on the external shunt specification.
3. There are 10 different kits to choose from, enough to meet your various needs.
4. The physical layer uses the UART to RS485 communication interface, the baud rate is 9600, 8 data bits, 2 stop bits, no parity.
5. The application layer uses the ModbusRTU protocol for communication and only supports function codes such as 0x03, 0x04, 0x06, 0x41, 0x42, etc.

Specifications:

This module is primarily used to measure DC voltage, current, active power, frequency, and power consumption. The module has no display function; data is read via the RS485 interface.

When the measured voltage exceeds the threshold, an alarm can be triggered.

Note:
The RS485 interface is a passive output, requires an external 5V power supply, and the external power supply must be >100mA.
When the input test voltage is less than 7V, an independent 5V working voltage must be supplied via the port USB.
Do NOT use the USB port provided by your PC as an independent power source, as this may damage your PC.
